Abstract: A closed loop control system based on pseudo rate modulator (PRM) may frequently oscillate due to its strongly nonlinear feature and uncertainty. And propellants exhausts extra when control system oscillates. A method is given to eliminate self excited oscillation via identifying the self excited oscillation period. The control parameters are modified according to the identification results. Finally the simulation results show that the given method is valid.

Key words: self excited oscillation, attitude control, Psudo rate modulator
